Print-media specificationsThis section contains information about specifications for the quality of print media, guidelines forprint media usage, and guidelines for print media storage.

General guidelinesSome print media might meet all of the guidelines in this manual and still not produce satisfactoryresults. This problem might be the result of improper handling, unacceptable temperature andhumidity levels, or other variables over which Hewlett-Packard has no control.

Before purchasing large quantities of print media, always test a sample and make sure that the printmedia meets the requirements specified in the HP LaserJet Printer Family Print Media Guideavailable at http://www.hp.com/support/ljpaperguide.

CAUTION Using print media that does not meet HP specifications can cause problems forthe printer, requiring repair. This repair is not covered by the Hewlett-Packard warranty orservice agreements.

CAUTION Use only paper designed for laser printers. Paper for inkjet printers may damagethe printer.

This printer accepts a variety of media, such as cut-sheet paper (including up to 100% recycled-fiber-content paper), envelopes, labels, transparencies, HP LaserJet glossy paper, HP LaserJet Toughpaper, HP LaserJet Photo paper, and custom-size paper. Properties such as weight, composition,grain, and moisture content are important factors that affect printer performance and output quality.Print media that does not meet the guidelines outlined in this manual can cause the followingproblems:

● Poor print quality

● Increased jams

● Premature wear on the printer, requiring repair

Paper and print mediaFor print-media specifications, see Media support tables on page 16.

Printing and storage environmentIdeally, the printing and media-storage environment should be at or near room temperature, and nottoo dry or too humid. Remember that paper is hygroscopic; it absorbs and loses moisture rapidly.

Heat works with humidity to damage paper. Heat causes the moisture in paper to evaporate, whilecold causes it to condense on the sheets. Heating systems and air conditioners remove most of thehumidity from a room. As paper is opened and used, it loses moisture, causing streaks andsmudging. Humid weather or water coolers can cause the humidity to increase in a room. As paper isopened and used it absorbs any excess moisture, causing light print and dropouts. Also, as paperloses and gains moisture it can distort. This issue can cause jams.

As a result, paper storage and handling are as important as the paper-making process itself. Paperstorage environmental conditions directly affect the feed operation and print quality.

ENWW Print-media specifications 13

http://www.hp.com/support/ljpaperguide

Care should be taken not to purchase more paper than can be easily used in a short time (aboutthree months). Paper stored for long periods can experience heat and moisture extremes, which cancause damage. Planning is important to prevent damage to a large supply of paper.

Unopened paper in sealed reams can remain stable for several months before use. Openedpackages of paper have more potential for environmental damage, especially if they are not wrappedwith a moisture-proof barrier.

The media-storage environment should be properly maintained to ensure optimum printerperformance. The required condition is 20° to 24°C (68° to 75°F), with a relative humidity of 45% to55%. The following guidelines should be helpful when evaluating the paper's storage environment:

● Print media should be stored at or near room temperature.

● The air should not be too dry or too humid (to moderate the hygroscopic properties of paper).

● The best way to store an opened ream of paper is to rewrap it tightly in its moisture-proofwrapping. If the printer environment is subject to extremes, unwrap only the amount of paper tobe used during the day's operation to prevent unwanted moisture changes.

● Avoid storing paper and print media near heating and air conditioning vents or near windowsand doors that are frequently open.

EnvelopesEnvelopes can be printed from Tray 1 or Tray 2. Select the type of envelope that you are using fromthe Print dialog box or the printer driver.

In your program, set the margins for the envelope. The following table gives typical address marginsfor a commercial #10 or DL envelope.

Table 1-3 Envelope specifications

Type of address Top margin Left margin

Return address 15 mm (0.6 inch) 15 mm (0.6 inch)

Delivery address 51 mm (2 inches) 89 mm (3.5 inches)

● For the best print quality, position margins no closer than 15 mm (0.6 inch) from the edges ofthe envelope.

● Avoid printing over the area where the envelope seams meet.

Envelope storage

Proper storage of envelopes helps contribute to print quality. Envelopes should be stored flat. If air istrapped in an envelope and creates an air bubble, then the envelope might wrinkle during printing.

Envelope construction

Envelope construction is critical. Envelope fold lines can vary considerably, not only betweenmanufacturers, but also within a box from the same manufacturer. Successful printing on envelopes


depends upon the quality of the envelopes. When selecting envelopes, consider the followingcomponents:

● Weight: The weight of the envelope paper should not exceed 90 g/m2 (24 lb) or jamming mightoccur.

● Construction: Before printing, envelopes should lie flat with less than 6 mm (0.25 inch) curl,and should not contain air.

● Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.

● Temperature: Use envelopes that are compatible with the heat and pressure of the printer. Thisprinter fusing temperature is 210°C (410°F).

● Size: Use only envelopes that are within the following size ranges.

Table 1-4 Envelope size ranges

Tray Minimum Maximum

Tray 1 or Tray 2 76 x 127 mm (3 x 5 inches) 216 x 356 mm (8.5 x 14 inches)

Envelopes with double side-seams

Double side-seam construction has vertical seams at both ends of the envelope rather than diagonalseams. This style might be more likely to wrinkle. Be sure the seam extends all the way to the cornerof the envelope as illustrated below.

1

2

Figure 1-8 Envelope double side-seam construction

1 Acceptable

2 Unacceptable

Envelopes with adhesive strips or flaps

Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must useadhesives that are compatible with the heat and pressure in the printer. The extra flaps and stripsmight cause wrinkling, creasing, or even jams and might damage the fuser.


LabelsSelect the type of label that you are using from the Print dialog box or the printer driver.

CAUTION To avoid damaging the printer, use only labels that are recommended for laserprinters. To prevent serious jams, always use Tray 1 or Tray 2 to print on labels. Never printon the same sheet of labels more than once or print on a partial sheet of labels.

When selecting labels, consider the quality of each component:

● Adhesives: The adhesive material should be stable at 210°C (410°F), which is the printerfusing temperature.

● Arrangement: Only use labels with no exposed backing between them. Labels can peel offsheets with spaces between the labels, causing serious jams.

● Curl: Before printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in anydirection.

● Condition: Do not use labels that have wrinkles, bubbles, or other indications of separation.

TransparenciesUse only Tray 1 or Tray 2 to print on transparencies. Select Transparencies from the Print dialogbox or the printer driver.

The printer supports printing on color transparencies. Use only transparencies that arerecommended for use in laser printers.

Transparencies that are used in the printer must be able to withstand 210°C (410°F), which is theprinter fusing temperature.

CAUTION To avoid damage to the printer, use only transparencies that are recommendedfor use in laser printers.

You can also use Tray 1 to print the first page ondifferent media than the rest of the document.

ENWW Install input devices 23

For information about loading special print media such as envelopes, labels, and transparencies, seePrint-media specifications on page 13.

To load Tray 1

1. Media guides ensure that the media is correctly fed into the printer and that the print is notskewed. Slide the media-width guides slightly wider than the print media.

2. Feed print media into Tray 1 with the side to be printed down, and the top, short edge in first.Make sure that the media is inserted far enough into the printer for the paper feed mechanismto grab the media. The paper will reach the sensor after 140 mm (5.5 inches) has been inserted.The printer will then pause for .5 second before it pulls the paper into the printer. HPrecommends holding the paper on both sides when inserting.

NOTE Light weight paper may buckle if held only on the short (far) edge as it isinserted. As paper is inserted, it trips the registration shutter. For light weight paper,holding it on both sides near the slot increases the ability for the paper to appropriatelytrip this shutter.


Installing supplies

Print cartridgesWhen a print cartridge approaches the end of useful life, the control panel displays a messagerecommending that you order a replacement. The printer can continue to print using the current printcartridge until the control panel displays a message instructing you to replace the cartridge.

The printer uses four colors and has a different print cartridge for each color: black (K), cyan (C),magenta (M), and yellow (Y).

Replace a print cartridge when the printer control panel displays one of the following messages:Replace yellow cartridge, Replace magenta cartridge, Replace cyan cartridge, Replace blackcartridge. The control panel display also indicates the color that should be replaced (unless agenuine HP cartridge is not currently installed).

To change the print cartridge

1. Turn off the printer.

2. Open the front door.

CAUTION Do not place anything on the transfer belt (ETB), which is located onthe inside of the front door.

3. Remove the used print cartridge from the printer.

● DC controller PCB

● Low-voltage power supply unit

● High-voltage power supply PCB

Main motor failure detectionThe CPU determines the main motor failure, stops the printer, and notifies the formatter of errorstatus, when it encounters the following conditions.

● Main motor start-up abnormality

The interval of the MAIN MOTOR SPEED DETECTION signal (/MAINMFG) does not becomethe specified interval after 1000 ms of the main motor drive start.

● Main motor rotation abnormality

The interval of the /MAINMFG signal stays at an irregular interval for 100 ms and longer afteronce it has become the specified interval.

Fan motor failure detectionThe CPU determines the fan motor failure and notifies the formatter when it encounters the followingcondition.

The FAN LOCK signal (FANLCK) is “H” for approximately 10 seconds and longer during fan motorrotation.


Image formation systemThe image formation system serves as the nerve center of the printer and forms a toner image onpaper. It is controlled by the DC controller. The DC controller controls the laser/scanner unit and thehigh-voltage power supply PCB to form an image on paper according to the VIDEO signals (VDO, /VDO) upon reception of a print command from the formatter. There is a memory tag inside eachcartridge. The memory tags read and write data according to the command from the DC controller.

The following figure illustrates the image formation system.

ENWW Image formation system 39

Figure 4-2 Image formation system


Image formation process

Figure 4-3 Image formation process


The principal process of image formation is described here. The print process can be broadly dividedinto 5 stages with 7 steps. A toner image is formed on paper as it goes through each process. Thefollowing figure illustrates the stages and steps of the print process as follows.

1. Electrostatic latent image formation stage

Forms an electrostatic latent image on the photosensitive drum.

Step 1: Primary charging

Step 2: Laser beam exposure

2. Developing stage

Makes the electrostatic latent image on the photosensitive drum surface visible by applying toner.

Step 3: Development

3. Transfer stage

Transfers a toner image on the photosensitive drum onto paper.

Step 4: Transfer

Step 5: Separation

4. Fuser stage

Fuses the toner image on paper.

Step 6: Fuser

5. ETB cleaning stage

Cleans the residual toner on the photosensitive drum.

Step 7: ETB cleaning

Latent image formationThis stage consists of two steps and forms an electrostatic latent image on the photosensitive drum.

When the last step in this stage is completed, a negative electrical charge remains in the unexposeddrum surface area by the laser beam and is removed from the exposed area. The image withnegative charge on the drum is called an “electrostatic latent image” as it is invisible to human eyes.


Figure 4-4 Latent image formation

Laser/scanner systemThe laser/scanner system forms latent images on the photosensitive drum according to the VIDEOsignals sent from the formatter. It consists of the laser driver PCB, the scanner motor, and so forth.The figure below illustrates the laser/scanner unit.

Figure 4-5 Laser beam exposure

Developing stageThe electrostatic latent image on the photosensitive drum surface is visualized by applying the tonerin this process. This printer utilizes the projection development method by the non-magnetic, single-component toner.


Figure 4-6 Developing stage

The toner has an insulating property and has negative charge potential from friction with the rotatingdeveloping cylinder and the developing blade surface.

The area of the photosensitive drum, where the laser beam is exposed, has higher potential than thetoner, which is charged negatively on the cylinder. When this area contacts the toner layer(negatively charged), the toner jumps onto the drum surface by the potential difference between thedrum surface and the cylinder (higher potential on drum side). This is called the projectiondevelopment and it visualizes the electrostatic latent image on the drum. The developing cylinder isapplied the AC bias in order to make the toner jump easier onto the drum surface and improve thecontrast of the output image.

This printer is able to adjust the image density by changing the potential difference between thecylinder and the photosensitive drum surface according to changes of the developing DC bias basedon the IMAGE DENSITY INFORMATION signal sent from the formatter.

The developing sheet improves the print quality and also prevents toner scattering.

Print cartridgeThe cartridge forms a visible toner image on the photosensitive drum. There are four print cartridges:magenta, cyan, yellow, and black; each having identical structure.


Figure 4-7 Print cartridge structure

Transfer belt (ETB)The ETB unit feeds paper as well as transfers toner onto the paper.

The ETB unit consists of the ETB, ETB feed roller, ETB driven roller, and color misregistration/density sensor unit.

As the main motor rotates the ETB feed roller, the ETB feed roller rotates the ETB belt. The transferroller and the ETB driven roller are engaged with the ETB.

During printing, the picked up paper is conveyed in between the ETB and the photosensitive drum,and simultaneously the toner image is transferred onto the paper. The ETB is also used for colormisregistration corrective control and the image stabilization control. The pattern image for the colormisregistration or image density determination is transferred onto the belt. This pattern image is readin the color misregistration/density sensor unit.

The following is the diagrammatic sketch of the ETB unit.


Figure 4-8 ETB unit

Transfer stageThe transfer stage is to transfer the toner image on the photosensitive drum surface onto paper.

Figure 4-9 Transfer stage


The toner on the photosensitive drum surface is transferred onto the paper according to the positivecharge from the back side of the paper. Each color’s toner image is transferred in order of M, C, Y,and K, and forms one toner image overlaying one color’s image on another.

Separation stage

Figure 4-10 Separation stage

The paper is separated from the drum by its elasticity (Curvature Separation). The static charge onthe back side of the paper is decreased with the electrostatic eliminator in order to stablize thefeeding operation and prevent the crescent spots of printing image under the low temperature andlow humidity environment.

Fusing stageThe toner image is fused onto the paper in this stage. The toner image transferred onto the paperthrough the transfer stage can be smeared easily by hands since it is only attracted to the paper bythe static electricity. The paper and the toner on it are fused by pressure, fused and secondarycolored by heat to be a permanent image.

Figure 4-11 Fusing stage

The toner image on the paper is fused onto the paper by using the on-demand fuser method in thisstep. This printer utilizes the ceramic heater with lower heat capacity, which warms up quickly, does


not require the power supply during STBY mode, and saves energy. As for the printer, the DCpositive bias is applied to the fuser pressure roller, so the transferred toner stays harder on the paperand toner scattering to the fuser film (offset) is prevented.


Pickup and feed systemThe pickup/feed system, which picks up and feeds paper, consists of the various feed rollers. Thisprinter has two pickup sources: the cassette and the manual feed slot, and one delivery source: theface-down tray. The following components are part of the pickup and feed system:

● Manual feed slot paper sensor (SR3): detects the presence of paper in the manual feed slot

● Cassette paper sensor (SR2): detects the presence of paper in the cassette

● DC controller controls the following to drive each feed roller:

● Main motor (M1)

● Fuser/delivery motor (M2)

● Pickup motor (M3)

● Solenoid (SL1)

● Solenoid (SL2)

● Solenoid (SL3)

● Photo sensors:

● SR1, SR4, and SR5 on the paper transport path detect the arrival and passage of paper

● SR9 detects the fuser pressure roller alienation in the fuser

● SR8 detects the paper width

The figure below illustrates the motors, solenoids, and sensors.

NOTE There is a short pause before the paper is picked up.

Manual feed slot pickup mechanismThis mechanism picks up one sheet of paper only that is inserted into the manual feed slot and theninto the printer. This printer does not have a pickup roller in the manual feed slot. Instead of a pickuproller, the registration roller picks up paper. The presence of paper in the manual feed slot isdetected by the manual feed slot paper sensor (SR3). The following is the operational sequence ofthe manual feed slot pickup.

1. If paper is set into the manual feed slot during STBY mode, the manual feed slot paper sensor(SR3) detects it.

2. When the paper is detected, the DC controller drives the pickup motor (M3) for 5 seconds. Thepaper is fed approximately 5 mm (0.2 inch) and is then caught by the registration roller.

3. After the above operational sequence, the paper is fed by the drive of the registration roller.

Paper feed mechanismThis mechanism feeds one sheet of picked up paper to the fuser. There is a paper width sensor inthe paper transport path to prevent temperature rise at the end of the fuser. It detects paper withwidths of shorter than 190 mm (7.5 inches). The following is the operational sequence of paper feed.

1. Paper skew is corrected by the registration shutter when the paper is fed into the printer.

2. Toner is transfered to the paper from the photosensitive drum and then the paper is fed to thefuser/delivery stage.

Skew correction by the registration shutterIf the paper fed into the printer is skewed, when it hits the registration shutter, it will be adjusted.Figure 4-13 Skew correction on page 52 illustrates how skewed paper is corrected by the registrationshutter.


Figure 4-13 Skew correction

Jam detectionThis printer is provided with the following paper detection sensors to detect the presence of paperand whether or not the paper feed is operating normally.

● Registration paper sensor (SR1)

● Pre-fuser paper sensor (SR5)

● Fuser delivery paper sensor (SR4)

The CPU determines a paper jam by checking whether or not paper is present at the sensor at thecheck timing. The check timing is stored in the memory of the CPU. If the CPU determines a jam, itstops the print operation and notifies the formatter of a jam occurrence.

For more information, see Clearing jams on page 100.

Elapsed time calibration will occur when the first job is sent after the elapsed time is exceeded.Use PML/PJL commands to configure the following intervals:

● Do not perform elapsed time calibration

● After 12, 24, 48, 96, or 168 hours (default is 48 hours) or more have elapsed since the lastcalibration (or power-on), and after 1-6 minutes (default is 15 minutes) of idle time from thefirst job after 12, 24, 48, 96, or 168 hours (default is 48 hours) have elapsed.

● On-demand calibration

Calibrate the printer using the printer control panel. For more information about printercalibration, see Printer calibration on page 146.

● New consumable calibration

When a new print cartridge is installed, the printer will calibrate.

NOTE When a new black print cartridge is replaced, a cleaning page will print beforethe printer calibrates.

If printing stops when the cartridge is out, requiring the user to either install a new cartridge orselect to print with toner out override, a calibration will not occur until the depleted cartridge isreplaced, printing resumes, and all jobs currently in the queue are finished or cancelled. Thiscould result in an interval of several pages where a new cartridge is using the old cartridge’scalibration data.

Clearing jams This section contains information about clearing jams.

Paper path

Figure 6-1 Paper path

For paper path sensor locations, see Figure 4-12 Paper pickup and feed system on page 50.


Common causes of paper jamsOccasionally, paper or other print media can become jammed during a print job. Some causesinclude the following events:

Cause Solution

The input trays are loaded improperly or overfilled. Remove any excess paper from the input tray. Make surethat the paper does not exceed the maximum stack heightmark in the input tray.

Tray 2 or optional Tray 3 is opened during a print job. Make sure that Tray 2 or optional Tray 3 is closed.

Too many sheets accumulated in the output area or sheetsblocked the output area.

Remove any accumulated sheets and clear the output area.For information about clearing jams from the output area,see Output jams on page 105.

The print media that is being used does not meet HPspecifications.

Use only paper that meets HP specifications. For moreinformation, see the HP LaserJet Printer Family Print MediaGuide or go to http://www.hp.com/support/ljpaperguide.

The environment in which the print media was stored is toohumid or too dry.

Make sure that the printer environment is within humidityspecifications. For more information, see Printing andstorage environment on page 13.

A supply item is installed incorrectly, causing repeated jams. Verify that all print cartridges and the ETB are correctlyinstalled.

Print media is skewed. Input tray guides are not adjusted correctly. Adjust input trayguides so they hold the print media firmly in place withoutbending it.

NOTE Do not fan paper. Fanning can create staticelectricity, which can cause the paper to sticktogether.

Print media is binding or sticking together. Remove paper, flex it, rotate it 180 degrees, or flip it over.Reload paper into the input tray.

Print media is removed before it settles into the output bin. Reset the printer. Wait until the page completely settles inthe output bin before removing it.

Print media is in poor condition. Replace the paper.

Print media is not picked up by the internal rollers fromTray 2 or Tray 3.

Remove the top sheet of paper. If the paper is heavier than163 g/m2 (43 lb), it may not be picked from the tray.

Print media has rough or jagged edges. Replace the paper.

Print media is perforated or embossed. This paper does not separate easily. Feed single sheetsfrom Tray 1.

The printer supply items have reached the end of life.Check the printer control panel for messages prompting areplacement of supplies, or print a supplies status page toverify the remaining life of the supplies.

Print media was not stored correctly. Replace the print media. Print media should be stored in theoriginal packaging in a controlled environment.

ENWW Clearing jams 101

http://www.hp.com/support/ljpaperguide

Where to look for jamsJams can occur in these locations:

● Inside the printer

● In input areas

● In the output area

● Paper path

The following illustration identifies the stages when jams can occur.

Figure 6-2 Jam locations and stages

1 Pickup stage

2 Feeder stage

3 Transfer/feed stage

4 Fusing/delivery stage


Find and remove the jam by using the instructions on the following pages. If the location of the jam isnot obvious, first look inside the printer.

Loose toner might remain in the printer after a jam. This problem should resolve itself after a fewsheets have been printed.

Each section below corresponds to an area where a paper jam could occur. Use the followingprocedures to clear the jam. In all cases, grasp the jammed paper by both corners and pull slowly toremove the paper.

Jams inside the printerUse the following instructions to clear jams from inside the printer.

CAUTION Jams in this area might result in loose toner on the page. If you get toner on yourclothes or hands, wash them in cold water. (Hot water will set the toner into the fabric.)


CAUTION Do not place anything on the transfer belt, which is located on theinside of the front door. Otherwise, the printer may be damaged, adverselyaffecting print quality.


2. Carefully grasp the jammed paper by both corners and pull slowly to remove the paper.

3. Close the front door.

Input jams

Tray 1If the jammed paper is easily accessible from the outside of the printer, grasp both edges of thepaper and firmly pull to remove. Otherwise, follow the directions for Tray 2.


Tray 2Open the front door of the printer and remove paper as indicated on the jam instruction label, locatedon the interior right side of the printer. Input jams are indicated on the label with the number 3.

Figure 6-3 Tray 2 input jam label

Output jams

Jams in the top bin

CAUTION Jams in these areas might result in loose toner on the page. If you get toner onyour clothes or hands, wash them in cold water. (Hot water will set the toner into the fabric.)

1. Carefully grasp the jammed paper by both corners and pull slowly to remove the paper from thetop bin.


2. Open and close the front door.

Pickup delay jamThe printer performs the retry control, which executes the pickup operation three times, to retrievethe pickup delay jam caused by the pickup error. When the registration paper sensor (SR1) does notdetect the leading edge of the paper within approximately 2.5 seconds (4.5 seconds for optionalcassette) after the pickup solenoid (SL1) is turned ON, the CPU tries to pick up the paper three times.

Pickup stationary jamThe CPU determines the pickup stationary jam when the registration paper sensor (SR1) does notdetect the trailing edge of the paper within approximately 8.6 seconds after it detects the leading edge.

Delivery delay jamThe CPU determines the delivery delay jam when the fuser delivery paper sensor (SR4) does notdetect the leading edge of the paper within approximately 6.6 seconds after the registration papersensor (SR1) detects the leading edge.

Wrapping jamThe CPU executes the wrapping jam detection after it assesses no delivery delay jam. The CPUdetermines the wrapping jam, when the fusing delivery paper sensor (SR4) detects the paperabsence before the time equivalent to paper passage of its length minus 40 mm (1.6 inches) after theSR4 detected the leading.

Delivery stationary jamThe CPU executes the delivery stationary jam detection after it assesses no wrapping jam. The CPUdetermines the delivery stationary jam, when the fuser delivery paper sensor (SR4) detects the paperpresence after the time equivalent to paper passage of its length plus 50 mm (1.9 inches) from whenit detected the trailing edge.

Start-up residual paper jamThe CPU determines the start-up residual paper jam when either the pre-fuser paper sensor (SR5)or the fuser delivery paper width sensor (SR4) detects the paper when the initial rotation is started.


Door open jamThe CPU determines the door open jam, when either the pre-fuser paper sensor (SR5) or the fuserdelivery paper width sensor (SR4) detects paper when a door open is detected.


Print problemsGetting informationThe following sections contain information about control panel messages, error reports, and availableservice menus.

Control panel messagesThe majority of the control-panel messages are intended to guide the user through typical operation.The control-panel messages indicate the status of the current operation, and include a page count onthe second line of the display, if appropriate. When the device is printing data, control-panelmessages indicate this status.

Understanding print-quality settingsPrint-quality settings affect how light or dark the print is on the page and the style in which thegraphics are printed. You can also use the print-quality settings to optimize the print quality for aspecific media type.

You can change the settings in the device properties to accommodate the types of jobs that you areprinting. The following settings are available, depending on the printer driver that you are using:

● Draft (600 dpi)

● Normal (Image REt 2400)

NOTE Changing the resolution can change the formatting of your text.

To temporarily change print-quality settings

To change the print-quality settings only for the current software program, open the propertiesthrough the Print Setup menu in the program that you are using to print.

To change print-quality settings for all future jobs

For Windows 98, Windows 2000, and Windows Me:

1. In the Windows system tray, click Start, select Settings, and then click Printers.

2. Right-click the device icon.

3. Click Properties (in Windows 2000, you can also click Printing Preferences).

Identifying and correcting printed image defectsUse the checklist and print-quality issues charts in this section to solve print-quality problems.

Print-quality checklist

General print-quality problems can be solved by using the following checklist:

1. Make sure that the paper or print media that you are using meets specifications. Generally,smoother paper provides better results.

2. If you are using a special print media such as labels, transparencies, glossy, or letterhead,ensure that you have printed by type.

3. Print a Configuration page and Supplies Status page at the device.

● Check the Supplies Status page to see if any supplies are low or empty. No information isprovided for non-HP print cartridges.

● If the pages do not print correctly, the problem is with the hardware.

4. Print a Demo page from the HP Toolbox. If the page prints, the problem is with the printer driver.

5. Try printing from a different program. If the page prints correctly, the problem is with theprogram from which you were printing.

6. Restart the computer and the device and try printing again. If the problem is not resolved,choose one of these options:

● If the problem is affecting all printed pages, see General print quality issues on page 139.

● If the problem is affecting only pages printed in color, see Solving issues with colordocuments on page 143.

Paper handling issuesThe following sections contains information about paper handling issues.

Wrong size/type mediaUse the following procedure to troubleshoot and resolve wrong size or type media problems.

1. Make sure that the software program is selecting the correct media size or type.

2. Make sure that the printer driver for the software program is correctly installed, configured, andcapable of requesting the desired media size and type.


3. Make sure that the paper guides are touching the edges of the stack of media.

4. If the size of media requested is not loaded in the tray selected, the printer draws media fromthe next default tray that contains the correct size. Load the correct media in the tray and makesure that the tray is adjusted correctly. Load the tray with enough media to complete the printjob. (See the HP Color LaserJet 1600 User Guide for information about configuring the inputtrays.)

Cannot select a tray or feature to useWhen you cannot select a tray or feature to use, use the following procedure to troubleshoot andresolve problems.

1. When the size of media requested is not loaded in the tray selected, the printer draws mediafrom the next default tray that contains the correct size. Load the correct media in the tray andmake sure that the tray is adjusted correctly. Load the tray with enough media to complete theprint job. (See the HP Color LaserJet 1600 User Guide for information about configuring theinput trays.)

2. Make sure that the driver for the software program is correctly installed, configured, and capableof requesting the desired media size and type, or feature.

Performance problemsTry the tips in this section if pages exit the device, but have nothing printed on them, or when thedevice does not print any pages.

Table 6-9 Performance issues

Problem Cause Solution

Pages print but are totally blank. The sealing tape might still be in theprint cartridges.

Verify that the sealing tape has beencompletely removed from the printcartridges.

The document might contain blankpages.

Check the document that you areprinting to see if content appears on allof the pages.

The device might be malfunctioning. To check the device, print aConfiguration page.

Pages print very slowly. Heavier media types can slow the printjob.

Print on a different type of media.

Complex pages will print slower. Proper fusing may require a slowerprint speed to ensure the best printquality.

Pages did not print. The device might not be pulling mediacorrectly.

See Paper handling issues on page 124.

The media is jamming in the device. Clear the jam.



The USB cable might be defective orincorrectly connected.

● Disconnect the USB cable at bothends and reconnect it.

● Try printing a job that has printedin the past.

● Try using a different USB cable.

Other devices are running on yourcomputer.

The device might not share a USBport. If you have an external hard drivethat is connected to the same port asthe device, the other device might beinterfering. To connect and use thedevice, you must disconnect the otherdevice or you must use two USB portson the computer.
